How to use JSON Diff

  1. Paste the original JSON document into the left editor (JSON A).
  2. Paste the modified JSON document into the right editor (JSON B).
  3. Click "Run diff" to normalize both payloads and see side-by-side highlighting of added, removed, and modified values.

Why use this local-first tool?

  • Semantic token-level JSON diffing that ignores minor whitespace formatting discrepancies.
  • Color-coded comparison table showing line additions in green and deletions in red.
  • Safe for sensitive database snapshots, configuration files, and API schema comparisons.
